Abstract

A handrail or a swing gate for fall restraint equipment comprising an outer rail constructed from a single, continuous piece of tubular metal, a midrail constructed from a single, continuous piece of tubular metal, and a toeboard constructed from a single, continuous piece of sheet metal, where the outer rail is constructed to receive portions of the midrail and toeboard for an integral construction.

Claims

1. A method for manufacturing a rail, wherein the rail comprises an outer rail, the method comprising:

providing a first continuous piece of tubular metal configured to be the outer rail, the first continuous piece of tubular metal having a first end and a second end, the first end comprising a first connecting portion configured to attach the first continuous piece of tubular metal to a platform structure, the second end comprising a second connecting portion configured to attach the first continuous piece of tubular metal to the platform structure, the platform structure being configured to allow a person to walk or stand thereon;

cutting out a first portion of the first continuous piece of tubular metal to define a left indentation between a left portion and a middle portion of the first continuous piece of metal;

cutting out a second portion of the first continuous piece of metal to define a right indentation between the middle portion and a right portion of the first continuous piece of tubular metal, wherein the left and right indentions are the only indentations in the first continuous piece of tubular metal;

folding the left portion with respect to the middle portion at the left indentation;

folding the right portion with respect to the middle portion at the right indentation;

attaching the first connecting portion to the platform structure at a first location so that the left portion is attached to the platform structure; and

attaching the second connecting portion to the platform structure at a second location so that the right portion is attached to the platform structure, wherein the first location is separate from the second location.

2. The method of claim 1, wherein:

the rail further comprises a midrail, the method further comprising connecting the midrail to the outer rail.

3. The method of claim 2, further comprising:

providing a second continuous piece of tubular metal configured to be the midrail.

6. The method of claim 1 further comprising:

connecting a toeboard to the outer rail; and

providing a continuous piece of sheet metal configured to be the toeboard.

7. The method of claim 6 further comprising:

cutting the continuous piece of sheet metal to define a tab on each distal end of the toeboard; and

cutting the first continuous piece of tubular metal to define a pair of slots in the outer rail,

wherein the step of connecting the toeboard to the outer rail comprises inserting each tab of the toeboard into each respective slot defined by the outer rail.

8. The method of claim 1 further comprising:

connecting at least one bracket to the rail.

9. The method of claim 1 further comprising:

connecting at least one hinge to the rail.

10. The method of claim 9 further comprising:

connecting a latch to the rail.

11. The method of claim 1 further comprising:

connecting the rail as a handrail to a structure.

12. The method of claim 1 further comprising:

connecting the rail as a swing gate to a structure.

4. The method of 3, further comprising:

cutting the first continuous piece of tubular metal to define a pair of apertures in the outer rail,

wherein the step of connecting the midrail to the outer rail comprises inserting each end of the midrail into each respective aperture defined by the outer rail.

5. The method of claim 4 further comprising:

cutting the second continuous piece of tubular metal to define a pair of tabs on each end of the midrail,

wherein the step of connecting the midrail to the other rail further comprises inserting each of the pair of tabs on each end of the midrail into each respective aperture defined by the outer rail.

13. A handrail comprising:

a top horizontal portion;

a left vertical portion connected to a left end of the top horizontal portion, the left vertical portion comprises a first end; and

a right vertical portion connected to a right end of the top horizontal portion, the right vertical portion comprises a second end,

wherein a base portion of each of the left and right vertical portions defines at least one aperture having a lower portion and an upper portion, the lower portion exhibiting a relatively greater circumference than that of the upper portion so that a fixture comprising a first part and a second part, wherein the second part exhibits a lesser circumference than the upper and lower portions and a first part exhibiting a lesser circumference than the lower portion but greater than the upper portion, may be received by the lower portion but is unable to pass through the upper portion,

wherein the first end comprises a first connecting portion configured to attach the left vertical portion of tubular metal to a platform structure, the second end comprising a second connecting portion configured to attach the right vertical portion to the platform structure, the platform structure being configured to allow a person to walk or stand thereon.

14. The handrail of claim 13 comprising:

a middle vertical portion connected between the left and right vertical portions.

15. The handrail of claim 13 wherein:

the left vertical portion, the top horizontal portion, and the right vertical portion are formed from one continuous piece of tubular metal.

16. The handrail of claim 13 wherein:

the at least one aperture defined by each base of the left and right vertical portions comprises a lower aperture and an upper aperture, wherein the upper aperture is located directly above the lower aperture.

17. The handrail of claim 16 wherein:

the lower portion of the upper aperture is generally circular while the upper portion is generally cylindrical such that the upper aperture resembles an inverted keyhole.
